[edk2-buildtools] Update the Guid.xref file to have only upper case GUIDs.

[Andrew F. <af...@ap...>]

I ran into some 3rd party INF files that use mixed case for the FILE_GUID and this was confusing my debugger Python scripts. I think it is better for the Guid.xref file to output the GUID strings in upper case.
